All steps from basic photoreceptor cells to modern eyes of different types can be seen in living animals. As for the rest, your questions are based on a mistake. A species - defined by the ability of members to breed with each other and have fertile offspring - does not and of course can not jump to a different species. There is no point in time where mutant members of a new generation could not breed with non muitant ones. Those who can’t breed by definition don’t breed, and the mutation dies with them. However, while each new step can breed with the preceding one or the following one, a large enough number of differences CAN mean that distant relatives can’t interbreed. This is true both of far ancestors and of different groups of what was formerly one single specie if they migrate to different areas and adapt to different selective pressures. All creatures are transitional, including me and you. The transition is simply small enough to make breeding with our near genetic relatives possible.
Frankly, you could read all this before you post.

I’ve read a lot of theories. Quite frankly I’m searching for a new wrinkle, theory or angle I can research.

As we’re all in transition as you say, can you give me some examples of creatures that are between species right now?

What are our nearest relatives btw? I ask because there isn’t a pat answer to that. Also, has there been any discovery that has really been proven to be part ape, part man? Proven. . .not extrapolation or outright fraud.

Has abiogenesis been witnessed anywhere or reproduced in any test? Has speciation been witnessed anywhere? Why the lack of studies or papers on the subject?

To save yourself time just give me some names or direct me to a location and I’ll do the legwork.
